E-book ad-hoc 通信の課題1. 教師のモバイル端末から生

徒に電子書籍を配信したい2. 配信を受けた生徒の端末か

ら、さらに配信できるとうれしい

BitTorrentみたいに配信できるとか ?

教室内での小規模な P2P ネットワークを形成できる

Page 21: A development of an Online Education System using Mobile Ad Hoc Networks

なにか使える道具は ?

• IP ネットワークが形成される前に、 WiFi やBluetooth で資源を発見したい– 既存の P2P フレームワーク、たとえば PIAX は、 IP ネット

ワークが前提なので使えない– OLSR より手軽に実装できる

• 探してみると…– UnderdarkMobile peer-to-peer mesh networking libraryhttp://virl.github.io/underdark/Allows apps on mobile devices to auto-discover and connect to each other via Wi-Fi and Bluetooth without any intervention from the user and without using any Internet connection.
